4. A coil is connected across a constant voltage supply at 200 V. The current drawn, initially, is 2,5 A and the temperature of the coil is 10'C. After
three hours the current has fallen to 2 A. Calculate the temperature rise of
the coil. The temperature coefficient of copper is 0,0043 per Cal 0°C.​

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.

Work = force × a. work b. energy c. distance d. momentum
