What is Ohm's Law and how is it applied in circuits?

a)

Ohm's Law defines the relationship between frequency and resistance.

b)

Ohm's Law is V = I * R, used to relate voltage, current, and resistance in circuits.

c)

Ohm's Law states that power equals voltage divided by current.

d)

Ohm's Law is used to calculate capacitance in circuits.

2.

How do you calculate the equivalent resistance of resistors in series?

a)

R_eq = R1 + R2 + R3

b)

R_eq = R1 - R2 - R3

c)

R_eq = R1 / R2 / R3

d)

R_eq = R1 * R2 * R3

3.

What is the formula for voltage in a series circuit?

a)

V_total = V_1 * V_2

b)

V_total = V_1 / V_2

c)

V_total = V_1 + V_2

V_total = V_1 - V_2

4.

Explain the Voltage Division Rule and its application.

a)

The Voltage Division Rule is used to calculate current in parallel circuits.

b)

The Voltage Division Rule allows for the calculation of voltage across components in a series circuit.

c)

The Voltage Division Rule applies only to AC circuits and not to DC circuits.

d)

The Voltage Division Rule determines the total resistance in a circuit.

5.

How do you calculate the equivalent resistance of resistors in parallel?

a)

R_eq = R1 + R2

b)

R_eq = 1 / (R1 + R2)
