To choose: The correct option.
Answer to Problem 5STP
The correct option is (C),
Explanation of Solution
Given:
A current of 2.0 A is flowing through a motor with resistance
Formula used:
The energy transformed in a motor, E and with a given resistance value, can be expressed in terms of the power dissipation and the time for which power is drawn, t, as
The power drawn by the motor is a function of its resistance R and current flowing through it, I which can be expressed as,
Calculation:
Substituting the current and resistance value, the power can be obtained as,
Now, substituting the value of power and time, the energy can be calculated as,
Conclusion:
Therefore, the correct option representing the energy transformed in the resistor is (C),
