Question

a current of 0.2 a passes through a 1.4 k ohm resistor what is the voltage across it​

Answer 1

Answer:

280V

Explanation:

1 kilo ohm=1000 ohm

V=IR

V=0.2×1.4×1000=280V

Answer 2

Given info : A current of 0.2A passes through a 1.4kΩ resistor.

To find : the voltage across the resistor is ..

solution : from Ohm's law, voltage across a wire is directly proportional to current passing through it.

i.e., V ∝ I

⇒ V = IR , where R is the resistance of the wire.

here, I = 0.2 A , R = 1.4kΩ = 1400Ω

so the potential across the resistor , V = 0.2A × 1400Ω = 280 volts

therefore the potential across the resistor is 280 volts.
