Question

8.
Observe the following table. Complete the table using Ohm's law
​

Answer 1

Ohm's law Formula = V = IR

Where

⇒V = Potential Difference

⇒I = Electric Current

⇒R = Resistance

i) Given

⇒I = 2A

⇒V = 120V

To Find

⇒Resistance (R)

Formula

⇒V=IR

⇒120V = 2A×(R)

⇒R = 120V/2A

⇒R = 60Ω

ii) Given

⇒I = 1.5A

⇒R = 60Ω

To Find

⇒Potential difference  (V)

Formula

⇒V= IR

⇒V = 1.5×60

⇒V = 90V

(iii) Given

⇒V = 60V

⇒R = 60Ω

To Find

⇒Current (I)

Formula

⇒V = IR

⇒60V = I60Ω

⇒I = 60/60

⇒I = 1A

 

Answer 2

Explanation:

to find

potential diffrence

1. =>V=IR
2. V=1.5×60
3. V=90V

to find

current

v=IR

60V=160

I=60/60

I =1A
