1.

2) Explain how will you find the measure of angle A if sin A = 05 using your scientific calculator.

Answer»

Answer:

Answer:

Given :-

CURRENT = 2.5 mA

Potential DIFFERENCE = 12 V

To Find :-

Resistance

Solution :-

Current = 2.5 × 10^-³

Now

Resistance = Potential difference/Current

Resistance = 12/2.5 10^{-3}10

−3

Resistance = 4.8 kΩ

Now

Given :-

Potential difference = 9 V

To Find :-

Current flow

Solution :-

At FIRST the total Net resistance in the battery

0.2 Ω, 12 Ω, 0.3 Ω, 12 Ω,0.412 Ω,0.5 Ω, 12 Ω, 2.22 Ω

=> 49.632 Ω

Now

We know that

V = IR

By putting value

9 = I(49.632)

9/49.632 = I

0.18 = I
