The value of electric current depends on the circuit and the applied voltage.
Electric current (I) is measured in amperes (A) and is given by Ohm’s Law:
V=IR
where V is voltage (in volts) and R is resistance (in ohms).
The current value varies based on the power source, resistance, and circuit components.
In household circuits, typical currents range from 1A to 15A, while in electronic devices, it is in milliamperes (mA) or microamperes (µA).
Hello
The value of electric current depends on the circuit conditions. Electric current (I) is defined as the rate of flow of electric charge and is given by the formula:
I = Q/t
where:
I = current (in amperes, A)
Q = charge (in coulombs, C)
t = time (in seconds, s)
In an electrical circuit, Ohm’s Law helps determine the current:
I = V/R
V = voltage (in volts, V)
R = resistance (in ohms, Ω)
The actual value of electric current in a circuit depends on the applied voltage, the resistance and the components present.
Hope this gives you the clarity you need.
