What is Circuit Analysis?

Back

Circuit Analysis is the process of finding the voltages across, and the currents through, every component in an electrical circuit.

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). Formula: V = I × R.

What is the unit of resistance?

Back

The unit of resistance is Ohm (Ω).

What is the formula to calculate current?

Back

Current (I) can be calculated using the formula: I = V / R, where V is voltage and R is resistance.

Front

What is the formula to calculate voltage?

Back

Voltage (V) can be calculated using the formula: V = I × R, where I is current and R is resistance.

What is the formula to calculate power in a circuit?

Back

Power (P) can be calculated using the formula: P = V × I, where V is voltage and I is current.

Front

What is a series circuit?

Back

A series circuit is a circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A parallel circuit is a circuit in which the components are connected across common points or junctions, providing multiple paths for the current.

What happens to the total resistance in a series circuit?

Back

In a series circuit, the total resistance (R_total) is the sum of the individual resistances: R_total = R1 + R2 + R3 + ...

Front

What happens to the total resistance in a parallel circuit?

Back

In a parallel circuit, the total resistance (R_total) can be calculated using the formula: 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...
