Question

EXERCISE HINTS: GETTING STARTEDM STUCK! Suppose the series resistors in the example are now 2.00 and 1.00 while the parallel resistors are 4.00 (top) and 2.00 (bottom), and the battery provides an emf of 40.0 V. (a) Find the equivalent resistance. eq5.00 How do resistors work together in series? How do they work together in parallel? (b) Find the currents I, I1, and I2 IYou used Ohm's law appropriately, but your value for the equivalent resistance was 11 = This is a correct expression for 11, but your value for I was incorrect, making this answer 12 = ncorrect, making this answer wrong too. A 2.66 wrong too. A 16 What factors affect the current in a circuit? A Need Help?Read it

Explanation / Answer

Here ,

a) for the equivalent resistance

Req = 2 + 1 + 4 * 2/(4 + 2)

Req = 4.33 Ohm

the equivalent resistance is 4.33 Ohm

b)

for the current I

I = Voltage/Resitance

I = 40/4.33 A

I = 9.24 A

the current I is 9.24 A

for the current in top

I1 = 9.24 * 2/(4 + 2)

I1 = 3.08 A

the current I1 is 3.08 A

I2 = 9.24 - 3.08

I2 = 6.16 A

the current I2 is 6.16 A
