Question

If a light bulb has a resistance of 10 Ohms, and it has 25 Amps of current

flowing, what is the Voltage of its battery?V=IR

Answer 1

250 Volts.

Step-by-step explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

`V = IR`

Where;

• V represents voltage measured in voltage.

• I represents current measured in amperes.

• R represents resistance measured in ohms.

Given the following data;

Resistance = 10 ohms

Current = 25 amps

Substituting into the equation, we have;

`V = 25 * 10`

V = 250V.

Therefore, the voltage of its battery is 250 volts.
