Question: A 2 3 . 7 0 V battery is used to supply current to a 1 4 k resistor. Assume the voltage drop across any
A V battery is used to supply current to a k resistor. Assume the voltage drop across any wires used for connections is negligible.
a
What is the current in mA through the resistor?
mA
b
What is the power dissipated by the resistor in mW
mW
c
What is the power input from the battery in mW assuming all the electrical power is dissipated by the resistor?
mW
d
What happens to the energy dissipated by the resistor?
The energy dissipated by the resistor is converted to electric potential energy.The energy dissipated by the resistor is converted to gravitational potential energy.The energy dissipated by the resistor is converted to elastic potential energy.The energy dissipated by the resistor is converted to heat.
