Question

What voltage is required to produce a current of 0.1 amps in a circuit with a 20 ohm resistor?

Answer 1

Answer:

2V

Explanation:

By Ohm's law, Voltage = Current * Resistance

= 0.1 * 20

= 2 Volt

Answer 2

• Current=I=0.1A
• Resistance=R=20ohm

Apply ohms law

• V=IR
• V=0.1(20)
• V=2.0
• V=2V
