Question on: WAEC Physics - 2010
Use the diagram above to calculate the current, I.
A
0.60A
B
0.97A
C
1.03A
D
5.00A
Ask EduPadi AI for a detailed answer
Correct Option: B
(\frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2})
= (\frac{1}{6} + \frac{1}{4})
R = (\frac{12}{5} = 2.5\Omega)
R = 2.4 + 10 = 12.4
V = IR
I = (\frac{v}{R} = \frac{12}{12.4} = 0.97)
