Question 1

Two resistors are connected to a battery. Voltmeters are connected in different parts of a circuit. Which equation is correct for the voltmeter readings?

Accepted Answer

$V = V_1 = V_2$

Answer

$V = V_1 	imes V_2$

Answer

$V = V_2 - V_1$

Answer

$V = V_1 + V_2$

Question 2

The circuit shows two lamps of equal resistance and three identical ammeters. Which ammeters give the same reading?

Accepted Answer

$A_2$ and $A_3$ only

Answer

$A_1$ and $A_2$ only

Answer

$A_1$ and $A_3$ only

Answer

$A_1$, $A_2$ and $A_3$

Question 3

A 3 $\Omega$ and a 6 $\Omega$ resistor are connected in a circuit as shown. State the arrangement of the resistors.

Accepted Answer

Parallel

Answer

Series

Question 4

What is the combined resistance of these two resistors?

Accepted Answer

$2 $ $\Omega$

Answer

$9 $ $\Omega$

Answer

$0.5$ $\Omega$

Answer

$3$ $ \Omega$

Question 5

The reading on the ammeter is 6 A. Given that the combined resistance of the two resistors is $2$ $\Omega$, what is the potential difference across the $3$ $\Omega$ resistor?

Accepted Answer

12 V

Answer

3 V

Answer

0.33 V

Answer

18 V
