Answer 1

Answer:

load is connected to a network. At the terminals to which the load is connected,

RTh=10Ω

and

VTh=40V.

The maximum possible power supplied to the load is: (a) 160 W (b) 80 W (c) 40 W (d) 1 W

Answer 2

Given: Resistance(R) = 10Ω

Voltage across the terminals = 40 V

To Find: Maximum power supplied to the load

Solution:

According to Ohm's Law,'The current through a conductor is proportional to the voltage across the conductor'.

V = IR, where V is voltage across the conductor, I is the current flowing through the conductor and R is the resistance of the conductor.

Voltage = $\frac{Work Done(W)}{Charge Flowing(q)}$                      ... 1

Current = $\frac{Charge Flowing(q)}{Time}$                     ....2

Power = $\frac{Work Done}{Time}$

Power = $\frac{V. q}{Time}$                          .... From 1

Power = VI                              .... From 2

Power = V ($\frac{V}{R}$)                         .... From Ohm's Law

Power = $\frac{V^{2} }{R}$

           = $\frac{40.40}{10}$

           = 160W

Therefore, maximum power supplied to the load is 160 Watt.
