Deaths associated with lightning in South Africa are about four times higher than the global average. A typical thundercloud maybe at a potential of 1,2 times 10^8V and the thunder strike may result in a charge transfer of 20C. CALCULATE THE CURRENT GENERATED DURING THE ABOVE THUNDER STRIKE IF THE CHARGE TRANSFER TAKES PLACE IN 1,1times 10-4s. AND ALSO CALCULATE THE AMOUNT OF ENERGY TRANSFERRED DURING THE STRIKE.
The average current is (20 Coulombs)/1.1*10^-4 s = 1.8*10^5 Amperes.
Multiply the charge transfer by the voltage difference to get the energy transfer.
20 Coulombs * 1.2*10^8 = 2.4*10^9 Joules
THANKS 4 HELPING ME OUT drwls :)
To calculate the current generated during the thunder strike, you can use the formula:
Current (I) = Charge (Q) / Time (t)
Given:
Charge transfer (Q) = 20 C
Time (t) = 1.1 × 10^-4 s
Substituting the values into the formula:
Current (I) = 20 C / (1.1 × 10^-4 s)
Now we can calculate the current:
I = 20 / (1.1 × 10^-4)
To simplify the calculation, we need to express 1.1 × 10^-4 in scientific notation:
I = 20 / (1.1 × 10^-4)
I = 20 / 1.1 × 10^-4
I = (20 / 1.1) × 10^4
Now let's calculate the current:
I = (20 / 1.1) × 10^4
I ≈ 18.18 × 10^4
I ≈ 1.818 × 10^5 A
Therefore, the current generated during the thunder strike is approximately 1.818 × 10^5 Amperes.
To calculate the amount of energy transferred during the strike, you can use the formula:
Energy (E) = Current (I) × Voltage (V) × Time (t)
Given:
Potential (V) = 1.2 × 10^8 V
Current (I) = 1.818 × 10^5 A
Time (t) = 1.1 × 10^-4 s
Substituting the values into the formula:
Energy (E) = 1.818 × 10^5 A × 1.2 × 10^8 V × 1.1 × 10^-4 s
Now we can calculate the energy:
E = 1.818 × 1.2 × 1.1 × 10^5 × 10^8 × 10^-4
To simplify the calculation, we combine the exponents:
E = 1.818 × 1.32 × 10^9 × 10^-4
Now we can calculate the energy:
E = 2.39576 × 10^9
Therefore, the amount of energy transferred during the thunder strike is approximately 2.39576 × 10^9 Joules.
