Question

5ohm 20ohm resistor are connected in parallel with a 16volt battery. find the current flowing​

Answer 1

Answer:

Just use the formula, 1/r1 + 1/r2 = 1/r to find the parallel resistance

1/5 + 1/20 = 1/r

4/20 + 1/20 = 1/r

5/20 = 1/4 = 1/r

therefore, r = 4 Ω

Now that you have the resistance, use the formula V/r = I to get the current.

V/r = I

16 V/ 4Ω = I

therefore I = 4 A

Thus the current flowing through the circuit is 4 Amperes
