Question

How much current would flow through a circuit that has 1000 ohms of resistance if powered by 3.0 volts?

Answer 1

Answer :

• 0.003 A

Given Information :

• Resistance (R) = 1000 Ω

• Potential difference or voltage (V) = 3.0 V

To calculate :

• Current (I)

Calculation :

By applying Ohm's law to the whole circuit,

$\boxed{\sf {V = IR}}$

Substituting the given values,

$\longmapsto \sf { 3.0 = I \times 1000}$

$\longmapsto \sf { \dfrac{3.0}{1000} = I }$

$\longmapsto \sf { \dfrac{3}{1000} = I }$

$\longmapsto \sf \red { 0.003 \: A= I }$

Therefore, 0.003 Ampere of current would flow through a circuit that has 1000 ohms of resistance if powered by 3.0 volts.

★ Ohm's Law :

• Ohm's law was stated by George Simon Ohm.

Accroding to Ohm's law, the electric current flowing through a conductor directly proportional to the potential difference across it ends, provided the temperature remain constant.

$\longrightarrow \sf { V \propto I }$

$\longrightarrow \sf { V = IR } \red { \bigstar}$

• R (resistance) is constant.
