Answer to Question #112651 in Electric Circuits for Peter

Question

Determine the power dissipated when a current of 10Ma flows through an appliance having a resistance of 8kΩ

Answer 1

As per the given question,

Current in the appliances $(i)=10\times 10^6A$

Resistance of the appliances $(R)=8\times 10^3 \Omega$

We know that, power dissipation in the appliances $(P)=i^2R$

$P=(10\times 10^6)^2\times8000=8\times 10^{17}watt$
