What is the unit of electric current?
Watt
Volt
Ohm
Ampere
Define Ohm's Law.
Ohm's Law: V = I * R, where V is voltage, I is current, and R is resistance.
Ohm's Law: I = V / R, where I is current, V is voltage, and R is resistance.
Ohm's Law: V = I + R, where V is voltage, I is current, and R is resistance.
Ohm's Law: R = V + I, where R is resistance, V is voltage, and I is current.
What is the difference between AC and DC?
AC reverses direction; DC flows in one direction.
AC is used in batteries while DC is used in power plants.
DC can be transmitted over long distances without loss.
AC is more efficient than DC.
What is a resistor and its function in a circuit?
A resistor is used to store electrical energy in a circuit.
A resistor is a component that generates heat in a circuit.
A resistor is a component that limits current flow in a circuit.
A resistor is a device that increases voltage in a circuit.
Explain the concept of capacitance.
Capacitance is the resistance to electric current flow.
Capacitance is the measure of voltage in a circuit.
Capacitance is the speed at which electric charge moves.
Capacitance is the ability to store electric charge, defined as C = Q/V.
What is the purpose of a diode in an electronic circuit?
To amplify electrical signals in a circuit.
To store electrical energy for later use.
