stion 7 If R- 2.0k2.C-40 mF, e-80v.Q-20 mC.and l 3.0 mA, what is the potential difference Vo Question 8 1 pts A capacitor in a single-loop RC circuit is charged to 53 % of its final potential difference in 4.4 s. What is the time constant for this circuit? Question 9 1 pts A certain brand of hot dog cooker applies a potential difference (120 V) to opposite ends of the hot dog and cooks by means of the joule heat produced. If 49 kJ is needed to cook each hot dog, what current is needed to cook 4 four hot dogs simultaneously in ó min? Note: The 4 hot dogs are in parallel. The total current (in all 4 is asked)

Explanation / Answer

Potential difference across resistor

Vr= 2*3=6 V

Potential difference across capacitor

Vc= 20/4= 5 V

=====

Vab= - 5+4+8= 7 V

Comment in case any doubt.. Goodluck
