Question

Calculate effective resistance and current in the circuit



a.effective resistance= 20 ohm, current= 0.5A

b.effective resistance= 20 ohm, current = 2A

c.effective resistance= 5 ohm, current = 0.5 A

d.effective resistance= 5 ohm, current= 2 A

​

Answer 1

Answer:

by ohms law

v=ir............

Answer 2

Answer:

V = lR

a. v = 10V

b. v = 40V

c. v = 2.5V

d. v = 10V

so, by option verification.a,d

now, effective resistance = 5 ohm(from picture)

so, option d is correct
