How would you connect the multimeter to measure current in series or in parallel?
In a series circuit, each circuit element has the same current. So, to measure current in a circuit, you must attach the multimeter in series. In a parallel circuit, each circuit measurement has the same voltage. So, to measure voltage in a circuit, you must attach your multimeter in parallel.
Can series current be measured?
A multimeter set to measure current can only measure the current going through it. So if you want to measure the current through a device like a resistor, you must arrange for the current passing through the resistor to also pass through the meter. The way to do that is to put the resistor and the meter in series.
How do you find current in a series and parallel circuit?
Now the Ohm’s law equation (ΔV = I • R) can be used to determine the total current in the circuit. In doing so, the total resistance and the total voltage (or battery voltage) will have to be used. For parallel branches, the sum of the current in each individual branch is equal to the current outside the branches.
Do you measure current in series or parallel?
No, Current is always measured through (in series with) a circuit element.
Why is current always measured in series?
Why is Ammeter Connected in Series? In a series connection, the current flowing through all the components of the circuit is the same. Ammeter aims at measuring the current in the circuit, hence it is connected in series so that the same current that is there in the circuit flows through it and gets measured.
Why do we measure current in series and not parallel?
Series: There is only one path, no matter how much current you have, it has to go through that path. So the current remains same in a series circuit because there is only one path. Parallel: There are more than one paths between two nodes. So the current can split into different quantities, one for each path.
Why current is always measured in series?
To measure the current of a circuit, the ammeter is connected in series in the circuit so that the current to be measured must pass through it. Since, the resistance of ammeter is low, so its inclusion in series in the circuit does not change the resistance and hence the main current in the circuit.
Why is ammeter used in series?
Ammeter aims at measuring the current in the circuit, hence it is connected in series so that the same current that is there in the circuit flows through it and gets measured. Ammeter has low resistance because we do not want to change the current that is flowing through the circuit.

How to use a multimeter to measure current?
The bulb shows the amount of current flowing in the circuit through its brightness. Now, to use a multimeter for measuring a current, you have to break the circuit for current to pass through the multimeter and readings to be taken. It’s not an easy thing, but it’s the best way to do it.
How do you measure the current in a circuit?
To measure the current, the circuit must be disconnected so that the meter actually becomes a part of the circuit. Current is the rate of electrical flow, so it’s like measuring liquid or gas flow with a turbine flow gauge. It must be directly in the path of the flow.
Do I need to put the meter in series with the circuit?
You do, however, need to put the meter in series with the circuit, having all the current flow through the meter as if it’s a wire in the circuit, as depicted in the drawing below. Turn off the power before you connect the meter, and use alligator clips! Why is this important?
How to connect a multimeter to a circuit breaker?
The red probe should get connected to the mA socket or the high current socket, which is usually marked 10A. The mA socket is marked with the maximum current. Now, break the circuit that you are taking readings on and connect your multimeter. The multimeter must be inserted in series in the circuit.
