The circuit shown in the figure below is connected for 1.50 min. (Assume R, = 7.60 N, R, = 1.60 N, and V = 10.0 V.) 5.00 Ω 3.00 Ω R2 1.00 N R 4.00 V

A 10 μF capacitor with an initial energy of 0.1 J is discharged through a 7.5 MΩ resistor. What is the initial charge on the capacitor? The charge, Q0 =  Units             . What is the current through the resistor when the discharge starts? The current, I0 =  Units             . Determine the potential difference across the capacitor and the rate at which the thermal energy is dissipating in the resistance 0.9 min after the discharge starts. The potential difference across C, VC =  Units             . The power dissipated in R, P =  Units             .

Referring to the given figure where V= 21 V, use source transformation to determine the current and power absorbed by the 8-0 resistor. 32 ww 82 3 A 102 The current absorbed by the 8-0 resistor is The power absorbed by the 8-0 resistor is A. W. ww

a. A heater consists of a variable resistor connected across an ideal voltage supply (no internal resistance). To increase the heat output, should you decrease the resistance or increase the resistance? Explain your answer.
