What is the current in a 10V circuit if the resistance is 2 Ω

By applying Ohm's law, the current in the circuit is equal to 5 Amperes.

Given the following data:

To determine the current in the circuit, we would apply Ohm's law:

Ohm's law states that at constant temperature, the current flowing through an electrical circuit is directly proportional to the voltage (potential difference) applied across its terminals and inversely proportional to the resistance in the electrical circuit.

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

Where;

Making I the subject of formula, we have:

Substituting the given parameters into the formula, we have;

Current, I = 5 Amperes.

5 Amperes

Explanation:

Current in the circuit = ?

Voltage in the circuit = 10Volts

Resistance = 2 Ω (Ω is the symbol for ohms, the unit of resistance)

Apply the formula:

Voltage = Current x Resistance

i.e V = IR

10V = I x 2 Ω

I = 10V / 2 Ω

I = 5 Amperes

Thus, the current in the circuit is 5 Amperes
