A 20.90 V battery is used to supply current to a 30 kΩ resistor. Assume the voltage drop across any wires used for connections is negligible.
(a)
What is the current (in mA) through the resistor?
0.6967
Correct: Your answer is correct.
mA
(b)
What is the power dissipated by the resistor (in mW)?
0.1456
Incorrect: Your answer is incorrect.
mW
(c)
What is the power input from the battery (in mW), assuming all the electrical power is dissipated by the resistor?
0.1456
Incorrect: Your answer is incorrect.
mW
