What is the total current from the voltage source in Figure for each switch position

If $R_1$ opens, the voltage across it (a) increases (b) decreases (c) stays the same

What is the total resistance of the circuit as seen from the voltage source for each position of the switch in Figure

If one of the resistors in a parallel circuit is removed, the total resistance (a) decreases by the value of the removed resistor (b) remains the same (c) increases (d) doubles

If $R_3$ opens, the voltage across it (a) increases (b) decreases (c) stays the same

For the circuit board shown in Figure earlier, determine the resistance between the following pins if there is a short between pins 3 and 4: (a) 1 and 2 (b) 2 and 3 (c) 2 and 4 (d) 1 and 4

For the circuit board shown in Figure , determine the resistance between the following pins if there is a short between pins 2 and 4 : (a) 1 and 2 (b) 2 and 3 (c) 3 and 4 (d) 1 and 4

If $R_2$ opens, the current through $R_1$ (a) increases (b) decreases (c) stays the same

The source voltage in Figure is $100 \mathrm{~V}$. How much voltage does each of the meters read?

When an additional resistor is connected across an existing parallel circuit, the total resistance (a) decreases (b) increases (c) remains the same (d) increases by the value of the added resistor

Develop a test procedure to check the circuit board in Figure to make sure that there are no open components. You must do this test without removing a component from the board. List the procedure in a detailed step-by-step format.

What is wrong with the circuit in Figure earlier if the meter reads $5.55 \mathrm{~mA}$ ?

What is wrong with the circuit in Figure earllier.

In Figure , the current and voltage measurements are indicated. Has a resistor opened, and, if so, which one?
