Answer:

b. 220 V

Explanation:

Let resistors be R1, R2, and R3 respectively.

Given the following data;

R1 = 20 ohms

R2 = 30 ohms

R3 = 60 ohms

Current = 2 Amperes

To find the voltage;

First of all, we would determine the total effective resistance (RT).

For series circuit;

RT = R1 + R2 + R3

RT = 20 + 30 + 60

RT = 110 Ohms

Next, we find the voltage using the formula;

Voltage = current * resistance

Voltage = 2 * 110

Voltage = 220 Volts
