Consider the circuit shown in the figure to find the power delivered to 6 Ohm resistance (in W). Given that Vs= 30 V

66.7 Watts

Explanation:

Let ohms, ohms and ohms. Since and are in parallel, their combined resistance is given by

or

The total current flowing through the circuit I is given

where

Therefore, the total current through the circuit is

In order to find the voltage drop across the 6-ohm resistor, we first need to find the voltage drop across the 1-ohm resistor :

This means that voltage drop across the 6-ohm resistor is 20 V. The power dissipated P by the 6-ohm resitor is given by

where's the following? you gotta add it to know what the choices are

explanation:
