Electric Current Formulas

Resistance Formula: Resistance (R) is calculated by the formula ( R = \frac{V}{I} ), where V is voltage and I is current.
Current Formula: Current (I) can be determined using the formula ( I = \frac{V}{R} ), relating it to voltage and resistance.
Voltage Formula: Voltage (V) is found with the formula ( V = R \times I ), connecting it with resistance and current.

Units of Measurement

Resistance Unit: The unit of resistance is Ohms (Ω), which quantifies how much a material opposes the flow of electric current.
Current Unit: Current is measured in Amps (A), indicating the rate of flow of electric charge.
Voltage Unit: Voltage is expressed in Volts (V), representing the potential difference that pushes electric current through a circuit.
Power Unit: Power is measured in Watts (W), which quantifies the rate at which energy is used or produced in a system.

Additional Formulas

Power Formula: Power can be calculated using ( W = V \times A ), indicating that power (W) is the product of voltage (V) and current (A).
Energy Formula: Energy usage is expressed in Kilowatt-hours (KWH), calculated by ( KWH = KW \times H ), where KW is kilowatts and H is hours.
Kilowatt-hours: KWH is a unit of energy that represents the amount of energy used over time, commonly used for electrical billing.
