Question
An electric heater has a resistance of 15.31 ohms and draws 7.84 amperes of current. What is the circuit voltage? (Round the FINAL answer to two decimal places.)
Solution
The voltage in a circuit can be calculated using Ohm's Law, which states that Voltage (V) equals Current (I) times Resistance (R). In this case, the current (I) is 7.84 amperes and the resistance (R) is 15.31 ohms.
Step 1: Write down the known values. I = 7.84 amperes R = 15.31 ohms
Step 2: Substitute the known values into Ohm's Law (V = I * R). V = 7.84 amperes * 15.31 ohms
Step 3: Calculate the voltage. V = 120.03 volts
So, the circuit voltage is approximately 120.03 volts. However, the question asks to round the final answer to two decimal places.
Therefore, the circuit voltage is 120.03 volts, rounded to two decimal places.
