What is Electric Current?

Back

Electric current is the flow of electric charge, typically measured in amperes (A). It represents the movement of electrons through a conductor.

Front

What is Voltage?

Back

Voltage, also known as electric potential difference, is the measure of the energy per unit charge available to drive the flow of current in a circuit, measured in volts (V).

Front

What is Resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω). It determines how much current will flow for a given voltage.

Front

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). It can be expressed as V = I × R.

What is a Series Circuit?

Back

A series circuit is a type of electrical circuit in which 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 type of electrical circuit in which components are connected across common points or junctions, allowing multiple paths for current to flow.

Front

How does increasing Voltage affect Current?

Back

If the voltage is increased while resistance remains constant, the current will increase according to Ohm's Law.

How does increasing Resistance affect Current?

Back

If the resistance is increased while voltage remains constant, the current will decrease according to Ohm's Law.

What is the formula to calculate Power in an electrical circuit?

Back

Power (P) can be calculated using the formula P = V × I, where P is power in watts (W), V is voltage in volts (V), and I is current in amperes (A).

Front

What is the unit of Electric Current?

Back

The unit of electric current is the ampere (A).
