Question

Answer

What are the basic

components of an

electrical circuit?

The basic components of an electrical circuit include a

power source (like a battery), conductors (wires), load

(such as a resistor or a bulb), and a control device (such as

a switch).

What is Ohm's Law and

why is it important in

electrical technology?

Ohm's Law states that the current flowing through a

conductor between two points is directly proportional to

the voltage across the two points and inversely

proportional to the resistance (V=IR). It is fundamental for

analyzing electrical circuits.

What is the difference

between AC and DC

current?

AC (Alternating Current) periodically reverses direction,

while DC (Direct Current) flows in one constant direction.

AC is commonly used in household power supplies,

whereas DC is used in batteries and electronic devices.

How do resistors affect

electrical circuits?

Resistors limit the flow of electric current, divide voltages,

and protect sensitive components by controlling the

current within circuits.

What safety precautions

should be taken when

working with electrical

circuits?

Safety precautions include turning off power before

working, using insulated tools, wearing protective

equipment, avoiding water, and following proper wiring

practices to prevent electric shocks and short circuits.

What is the significance of

a fuse in an electrical

circuit?

A fuse is a safety device that protects electrical circuits by

breaking the circuit if the current exceeds a safe level,

preventing damage and potential fire hazards.

What units are used to

measure voltage, current,

and resistance?

Voltage is measured in volts (V), current in amperes (A),

and resistance in ohms (Ω).

What is the purpose of a

multimeter in electrical

technology?

A multimeter is an instrument used to measure voltage,

current, and resistance in electrical circuits, helping

diagnose and troubleshoot electrical problems.

How does a capacitor

function in an electrical

circuit?

A capacitor stores and releases electrical energy by

accumulating charge on its plates, and it is used for

filtering, smoothing, and tuning signals in circuits.

What is the difference

between series and parallel

circuits?

In a series circuit, components are connected end-to-end

so the same current flows through all components. In a

parallel circuit, components are connected across the

same voltage source, so the voltage is the same across

each component but the current divides.
