Question

A current of 0.8A flow through a resistance of 30ohm. calculate the voltage across it?​

Answer 1

Given:

Current flow = 0.8 Ampere

Resistance value = 30 ohm

To Find: Voltage across the resistance

Calculation:

According to Ohm's Law:

• "Voltage across any load/resistor is directly proportional to the current flowing through that resistor."

• V ∝ I

• V = IR, where R is the proportionality constant i.e. resistance.

• Voltage here is expressed in Volt, Current is expressed in Ampere and Resistance is expressed in Ohm.

V = I * R

V = 0.8 * 30 = 24 Ω

Answer:

Value of voltage is 24 Ω.
