Question

If a electrician measures the current of a circuit to be 100 Amps and the circuit is only designed to have a current of 80 Amps, which of the following is the best explanation of what has happened to the circuit ?
A. a There are too many batteries in the circuit.
B. There are too many resistors in the circuit.
C. A battery in the circuit is missing.
D. A resistor in the circuit is missing.

Answer 1

There are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.

Current in the circuit

The current in the circuit is determined by applying Ohms law as shown below;

V = IR

where;

• I is the current
• V is the voltage
• R is the resistance

I = V/R

At a constant resistance of the circuit, the current in a circuit will increase when the emf of the circuit increases.

Thus, we can conclude that, there are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.
