You would find the potential difference aka voltage, but more specifically it would be just the voltage that the resistor uses and not the whole circuit.
But if you want the voltage value it’s V=IR so whatever the current is multiply it by the 45 ohm resistor value
yes is is true cuz when you hold the thermometer by a bulb the heat coming from the bulb will increase the thermometer
Answer:
64 Watts is 12dB greater than 4 Watts
Answer:
Explanation:
We shall apply Gauss's theorem for electric flux to solve the problem . According to this theorem , total electric flux coming out of a charge q can be given by the following relation .
∫ E ds = q / ε
Here q is assumed to be enclosed in a closed surface , E is electric intensity on the surface so
∫ E ds represents total electric flux passing through the closed surface due to charge q enclosed in the surface .
This also represents total flux coming out of the charge q on all sides .
This is equal to q / ε where ε is a constant called permittivity which depends upon the medium enclosing the charge . For air , its value is 8.85 x 10⁻¹² .
If charge remains the same but radius of the sphere enclosing the charge is doubled , the flux coming out of charge will remain the same .
It is so because flux coming out of charge q is q / ε . It does not depend upon surface area enclosing the charge . It depends upon two factors
1 ) charge q and
2 ) the permittivity of medium ε around .
Great question the answer is -25x.
