Battery
The measured value of the current is I = 3.1 ± 0.2 A and that of the voltage is V = 14 0.5 V. The resistance of
the circuit (in N) can be calculated using the formula, R = V/I,
Calculate the,

A Christmas light is made to flash via the discharge of a capacitor. The effective duration of the flash is 0.21 s (which you can assume is the time constant of the capacitor), during which it produces an average 35 mW from an average voltage of 2.85 V.
What is the resistance, in ohms, of the light?
(a) What is the internal resistance (in N) of a voltage source if its terminal voltage drops by 3.10 V when the current
supplied increases by 7.00 A?
Ω
(b) Can the emf of the voltage source be found with the information supplied?
O Yes, emf can be found using another equation.
No, the voltage source does not have an emf.
O No, there is only one independent equation, so only the resistance can be found.
O Yes, emf can be found using Ohm's law.
