Question

A simple electric circuit consists of a constant-voltage power supply and a variable resistor. What effect does reducing the resistance have on the current in the circuit and on the power output of the power supply?

Answer 1

Current will increase and power will also increase

Step-by-step explanation:

We have given that electric circuit is constant voltage and variable resistor

We have to tell the effect of change of resistance of the circuit on thr current and power output

We know that current is given by

`i=(V)/(R)`, from the relation we can see that current and resistance are inversely proportional so is we reduce the resistance then current will increase

And we know that power = voltage × current

So if current will increase then power output will also increase
