Question

Use the circuits shown to solve each of the following:

Answer 1

1. R = 8 ohms 2. V = 32 volts

Explanation:

1. We have,

Voltage, V = 16 V

Current, I = 2 A

We need to find the resistance of the circuit. Using Ohm's law,

V = IR

So,

`R=(V)/(I)\\\\R=(16)/(2)\\\\R=8\ \Omega`

2. Current, I = 8 A

Resistance, R = 4 ohms

We need to find the voltage of the circuit. Using Ohm's law again,

V = 8 × 4

V = 32 volts

Hence, this is the required solution.
