Answers
Solution:-
Given:-
=> Resistance ( R ) = 50Ω
=> Current ( I ) = 5 A
To find
:- Value of potential difference
Formula
:- V = IR
Now put the value on formula
:- V = 5A × 50Ω
V = 250V
Option B is correct

Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists.
E = I x R
When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.
Named for German physicist Georg Ohm (1789-1854),

Explanation:
Given
⇒Tanθ = 20/21
To Find
⇒(1-Sinθ + Cosθ)/(1+Sinθ+Cosθ)
First of all We have to find Sinθ and Cosθ
So take
⇒Tanθ = 20/21 = Perpendicular(p)/Base(b)
We get
⇒Perpendicular = 20 , Base(b) = 21 and Hypotenuse(h) = h
Using Pythagoras theorem
⇒h² = p² + b²
⇒h² = (20)² + (21)²
⇒h² = 400 + 441
⇒h² = 841
⇒h = √(841)
⇒h = 29
We get
⇒Perpendicular = 20 , Base(b) = 21 and Hypotenuse(h) = 29
Then
⇒Sinθ = P/h and Cosθ = b/h
⇒Sinθ = 20/29 and Cosθ = 21/29
Now Put the value on
⇒(1-Sinθ + Cosθ)/(1+Sinθ+Cosθ)
⇒(1-20/29 + 21/29)/(1+20/29 + 21/29)
⇒{(29-20+21)/29}/{29+20+21)/29}
⇒{(50 - 20)/29}/{(50+20)/29}
⇒(30/29)/(70/29)
⇒30/29 ×29/70
⇒30/70
⇒3/7
Answer = 3/7
