Answer:
The power dissipated by the resistor can be calculated as [tex]P = I^{2} R[/tex] .
Explanation:
- Joules heating law states that any conductor passed with the electric current produces heating effect which is the electric power loss.
- The given circuit has, [tex]R = 75 ohm[/tex] resistor (the unit is wrong i question because resistor's unit is ohm not Ampere).
- Current flowing through the circuit is [tex]I = 2.0 A[/tex].
- By using joules heating theory, [tex]P = I^{2} R[/tex],
[tex]or,[/tex] [tex]P = 2^{2} * 75[/tex]
[tex]or,[/tex] [tex]P= 4*75[/tex]
[tex]or[/tex], [tex]P= 300 W[/tex].
- So the power dissipated by the resistor in the circuit is 300 W.
