The total current through the circuit is 0. 19A
<h3>How to determine the current</h3>
We have the formula for power to be;
Current, I = V/R
Voltage = 7. 7V
Resistance in parallel = R1R2/ R1 + r2
Resistance in parallel = = = 41. 40 Ohms
Current = = 0. 19 A
Thus, the total current through the circuit is 0. 19A

2,450 Joules, kinetic energy is 1/2 mass x velocity squared.
A. To solve for part A, we use the formula of Young’s
double slit equation:
x = λ L m / d<span>
</span>Where,
x = distance between adjacent dark lines or fringes =
12.5 cm = 0.125 m
λ = wavelength of light = 600 × 10^-9 m
L = distance from the two sources of light to
the screen = 1.2 m
m = number of fringes = 10 (tenth) – 1 (first)
= 9
d = separation of slits = unknown
Rearranging the equation in terms of d and
plugging in the values:
d = λ L m / x
d = (600 × 10^-9 m) (1.2 m) (9) / 0.125 m
d = 5.184 × 10^-5 m
d = 51.84 μm
B. The formula for path difference is:
path difference = (2 m + 1) (λ / 2)<span>
path difference = (2 * 9 + 1) (</span>600 × 10^-9 m / 2)
<span>path
difference = 5.7 × 10-6 m</span>
<span>path difference = 5.7 μm</span>
