6) You connect resistors of 1.0 12, 2.0 12, and 3.0 12 across a battery as shown in the figure. The current in the resistors is given by I1, I2, and 13, respectively. If the current through the 3.0 22 resistor is 13 = 3.0 A, 11 12 13 V 112 12 12 a) What is the current in the other two resistors? (3 points) b) What is the voltage across the three resistors? (2 points)

Answers

Current through 3 ohm resistor=3 A.

Now, voltage=current*resistance.

So, voltage across 3 ohm resistor=3*3=9 V.

Now, since all the resistors are in parallel, voltage across them is the same. So, voltage across all of them is 9 volts.

Now,current through 1 ohm resistor=i1=voltage/resistance=9/1=9 A.

Similarly ,current through 2 ohm resistor=i2=voltage/resistance=9/2=4.5 A.

a) current i1=9 A and current i2=4.5 A.

b) voltage=9 volts
