Explanation:
It is given that,
Input voltage, 
Input current, 
Output current, 
Number of turns in the secondary side of transformer, 
We need to find the number of turns in the primary side of the transformer. The current to the number of turns in the input and output is given by :

Substituting all the above values
So,

So, the number of turns in primary side of the transformer is 5885.

Answer:</h2>
(a) 10.00V
(b) 0.5V
<h2>
Explanation:</h2>
(a) The power(P) supplied by a resistor of resistance (R) when a voltage(V) is passed across is given by;
P = V² / R ------------------(i)
From the question;
P = 5.00W
R = 20.00Ω
Substitute these values into equation (i) as follows;
5.00 = V² / 20.00
V² = 5.00 x 20.00
V² = 100.00
V = 
Solve for V;
V = 10.00V
Therefore, the maximum voltage that can be applied without harming the resistor is 10.00V
(b) By Ohm's law the current (I) flowing through a resistor of resistance (R) when a voltage (V) is applied is given by;
V = I x R
=> I = V / R ----------------(ii)
Substitute the values of V and R into equation (ii) as follows;
I = 10.00 / 20.00
I = 0.5A
Therefore, the current through the resistor is 0.5A
