Power And Energy Through Resistor

Power And Energy Through Resistor#

A 23 \(\textrm{ V}\) battery is used to supply current to a {{params.R} \(\rm\ k\Omega\) resistor. Assume the voltage drop across any wires used for connections is negligible.

Part 1#

What is the current through the resistor?

Answer Section#

Please enter a numeric value.

Part 2#

What is the power dissipated by the resistor?

Answer Section#

Please enter a numeric value.

Part 3#

What is the power input from the battery, assuming all the electrical power is dissipated by the resistor?

Answer Section#

Please enter a numeric value.

Part 4#

What happens to the energy dissipated by the resistor?

Answer Section#

  • It is converted into light energy.

  • It is converted into heat.

  • It is converted into chemical energy.
