What is the symbol of resistance?

• V

• I

• R

• P

What is the definition of ohms law?

• Resistance = Voltage ÷ Current

• Voltage = Current ÷ Resistance

• Current = Resistance ÷ Voltage

• Resistance = Current ÷ Voltage

Refer to fig.8; what is the total resistance?

• 2.24 kΩ

• 22.4 kΩ

• 2.24 Ω

• 22.4 Ω

What does Kirchhoff’s voltage law states?

• The sum of the voltage drops around a closed circuit is equal to the supply voltage (Vs)

• The sum of the current drops around a closed circuit is equal to the supply voltage (Vs)

• The algebraic sum of the currents entering at a point in a circuit is equal to the algebraic sum of currents leaving the point.

• The algebraic sum of the voltage entering at a point in a circuit is equal to the algebraic sum of current leaving the point.

What will happen to the total circuit resistance value (Rt) if resistors where connected in series?

• Decreases

• Increases

• Stays the same

• Doubles in value

what is the total resistance of the circuit?

• 1/Rt =1/ R1 + 1/R2 + 1/R3.

• 1/R1 = 1/(Rt + R2 + R3).

• Rt =R1 + R2 + R3.

• 1/Rt =1/ (R1 + R2 + R3).

What is symbol of current?

• V

• I

• R

• P

What will the current value be flowing in two different resistors (R1 & R2) connected in series?

• The same current value will flow in each resistor (R1 & R2)

• Different current value will flow in each resistor (R1 & R2)

• Half the current value will flow in resistor R1

• Doubles the current value flow in resistor R2

What law is fig. 10 applying?

• Kirchhoff’s voltage law state

• Kirchhoff’s current law state

• The Ohms law

• The Lanzs law

What will happen to the total circuit resistance value (Rt) if resistors where connected in parallel?

• Decreases

• Increases in value

• Have in value

• Quarter in value
