Question

You measure the voltage difference of a circuit to be 5 V and the resistance to be 1,000 ohms.

Answer 1

Answer:

The current in the circuit will be $5\times 10^{-3}\ Ampere$.

Explanation:

Given:

Voltage difference = V = 5 V

Resistance              = R = 1000 ohms

To Find:

Current, I = ?

Solution:

Ohm's Law:

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

i.e  I ∝ V

∴ V = I × R

Where, I = current

           V = voltage

           R = resistance

Substituting the values of V and R we get

∴ 5 = I × 1000

$I = \frac{5}{1000} \\I=0.005\ Ampere\\I=5\times 10^{-3}\ Ampere$

Therefore, the current in the circuit will be $5\times 10^{-3}\ Ampere$.
