Calculating the Current in the Circuit
To calculate the percentage change in electric current when the potential difference is increased from 100 volts to 200 volts, we need to first calculate the current in the circuit. We can use Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.
Using Ohm's Law, we can calculate the current in the circuit as:
I = V/R
Where I is the current in the circuit, V is the potential difference across the circuit, and R is the resistance of the bulb.
Substituting the given values, we get:
I = 100/1000
I = 0.1 A
Therefore, the current flowing through the circuit is 0.1 A.
Calculating the New Current
Now, let's calculate the new current when the potential difference is increased to 200 volts. Using Ohm's Law again, we get:
I' = V'/R
Where I' is the new current in the circuit, V' is the new potential difference across the circuit, and R is the resistance of the bulb.
Substituting the given values, we get:
I' = 200/1000
I' = 0.2 A
Therefore, the new current flowing through the circuit is 0.2 A.
Calculating the Percentage Change
To calculate the percentage change in electric current, we can use the formula:
Percentage change = (|I' - I|/I) x 100
Where |I' - I| is the absolute difference between the new current and the original current.
Substituting the values, we get:
Percentage change = (|0.2 - 0.1|/0.1) x 100
Percentage change = 100%
Therefore, the percentage change in electric current when the potential difference is increased from 100 volts to 200 volts is 100%.
To calculate the percentage change in electric current when the potential difference is increased from 100 volts to 200 volts, we need to first calculate the current in the circuit.

I' = 0.2 A
Therefore, the new current flowing through the circuit is 0.2 A.

To calculate the percentage change in electric current, we can use the formula:
Percentage change = (|I' - I|/I) x 100
Where |I' - I| is the absolute difference between the new current and the original current.
Substituting the values, we get:
Percentage change = (|0.2 - 0.1|/0.1) x 100
Percentage change = 100%
Therefore, the percentage change in electric current when the potential difference is increased from 100 volts to 200 volts is 100%.

R=1000 ohm
Initial V=100 V
Final V=200 V
Initial I=Initial V/R=100/1000=0.1A
Final I=Final V/R=200/1000=0.2A
Percentage Change=100%
(probably)
Initial V=100 V
Final V=200 V
Initial I=Initial V/R=100/1000=0.1A
Final I=Final V/R=200/1000=0.2A
Percentage Change=100%
