Q: What is the relationship between voltage, current, and resistance in a DC circuit, as defined by Ohm's Law?

V = I * R — Ohm's Law states Voltage (V) equals Current (I) multiplied by Resistance (R).

Q: In a series circuit, what is the relationship between the total resistance (Rt) and the individual resistances (R1, R2, R3...)?

Rt = R1 + R2 + R3... — In a series circuit, the total resistance is the sum of all individual resistances.

Q: In a parallel circuit, what is the relationship between the total resistance (Rt) and the individual resistances (R1, R2, R3...)?

1/Rt = 1/R1 + 1/R2 + 1/R3... — In a parallel circuit, the reciprocal of total resistance equals the sum of the reciprocals of individual resistances.

Q: What is the unit of measurement for electrical power?

Watt (W) — Electrical power is measured in Watts (W).

Q: What formula represents the power (P) dissipated in a resistor with voltage (V) and resistance (R)?

P = V^2 / R — Power is calculated as the square of voltage divided by resistance (P = V^2 / R).

Q: What is Kirchhoff's Current Law (KCL) based on?

Conservation of charge — KCL is based on the conservation of electric charge. Incoming current equals outgoing current at a node.

Q: What is Kirchhoff's Voltage Law (KVL) based on?

Conservation of energy — KVL is based on the conservation of energy. The sum of voltage drops and rises around a closed loop is zero.

Q: What is the equivalent resistance of two resistors, 10 ohms and 20 ohms, connected in parallel?

6.67 ohms — 1/Rt = 1/10 + 1/20; Rt = 6.67 ohms.

Q: If a 12V battery is connected to a 4-ohm resistor, how much current flows through the resistor?

3 A — Using Ohm's Law (I = V/R), I = 12V / 4? = 3A.

Q: What is the effect of increasing the voltage in a DC circuit, assuming resistance remains constant?

The current increases. — Increasing voltage directly increases current (I = V/R).
