Question

Refer to the figure. What is the current through the 2.0 Ohm resistor? 0.33 A 1.2 A 7.0 A 2.0 A A 9.0 V batters is connected to two resistors in series. If the resistors fuse resistances of 410.0 Ohm and 280. 0 Ohm, what is the voltage drop across the 280.0 Ohm resistor? 3.7 V 13 V 5.4 V 6.2 V What is the current through resistor R-1 in this circuit? 0.022 A 0.10 A 0.044 A 0.20 A A 13 mu F capacitor is connected in series with 21 k Ohm resistor. A 9 V battery is added in series with the capacitor and resistor when a switch is closed. What is the voltage between the plates of the capacitor 15 ms after closing the switch? 0.95 V 19 V 0.48 V 1.9 V

Explanation / Answer

(1) Using KVK in left closed loop Let current I1 is passing through it.

moving in anti clockwise direction ..

10 I1 -10 =0

I1=1 A

Now using KVL in right closed loop ..moving in anti clockwise direction

Let current through it is I2

-2I2-10I1 +14=0

2I2+10I1=14

now putting I1=1 A in above equation

2I2=14-10

I2=2 A ANS Option D.
