Current through 1000 Ohms = 48/1000 = 0.048.
Current through 3000 Ohms = 48/3000 = 0.016.
Current through 5000 Ohms = 48/5000 = 0.0096.
Current through 8000 Ohms = 48/8000 = 0.0796.
Total Current is 0.0796 mA Therefore power dissipated is 0.0796 mA*48V = 3.8208.
Current through 3000 Ohms = 48/3000 = 0.016.
Current through 5000 Ohms = 48/5000 = 0.0096.
Current through 8000 Ohms = 48/8000 = 0.0796.
Total Current is 0.0796 mA Therefore power dissipated is 0.0796 mA*48V = 3.8208.

If All current is add so this total current is 0.0796.
Current through 3000 Ohms = 48/3000 = 0.016.

By using network reduction techniques calculate parellel resistance and calculate the power supplied by source by using v*v/r it must be equall to dissipated power.

Find total current from supply by applying current division rule at parallel resistors. After finding total curr multiply it by 48v to get total power.

1/R = 199/120.
R = 120/199 = 0.6030150754 Kohm.
= 603.01 ohm.
It is approximately equal to 603 ohm.
P = VI = V*V/R.
= 48*48/603.
= 3.820895.

Firstly calculate the equation resistance then current through circuit by ohms law, then finally we can calculate power by p=vi or by p=i^2/r.

If R1, R2 are connected in series, then total resistance = R1+R2.
If they are connected in parallel, total resistance = (R1*R2) / (R1+R2).
If they are connected in parallel, total resistance = (R1*R2) / (R1+R2).

In any resistive ckt the total power supplied by voltage source must be dissipated across the resistors in that network.

If the two leads of resistor is connected to the leads of another one. Then we can say that resistors are in parallel.
