Question

A car panel lamp has a resistance of 33 ohms when it is placed across a 12 V battery. What is the current through the circuit?

Answer 1

The current through the circuit is calculated as 0.36 A.

Given:

Resistance (R) = 33 Ohms

Volt of the battery (V) = 12 V

To find:

The current through the circuit =?

Formula to be used:

`\text {Current }(I)=\frac{\text {Volt}(V)}{\text {Resistance}(R)}`

Calculation:

The current is given by the formula:

`\text {Current }(I)=\frac{\text {Volt}(V)}{\text {Resistance}(R)}`

`\Rightarrow I=(12)/(33)`

`\therefore I=0.36 \ A`

The flow of electron across the circuit generates a power which is called as electricity or power. It is basically dependent on the voltage and resistance.

Thus, for a car lamp with 33 Ohms resistance and 12 V battery, the current through the circuit is calculated as 0.36 A.

Answer 2

Step-by-step explanation:According to Ohm's law expressed in the form of an equation is V = RI, where V is the electrical potential in volts, I is the current in amps and R is the resistance in ohms; clearing we get that I = V / R, having 12 V / 33Ω = 0.36 Amps
