What is the resistance in a circuit that carries a 0.75 A current when powered by a 1.5 V battery?
2 answers:
Answer : The resistance in the circuit is, 2 ohm
Solution : Given,
Voltage = 1.5 V
Current in the circuit = 0.75 A
According to the Ohm's law, the current passing through the conductor is directly proportional to the voltage and is inversely proportional to the resistance.
Formula used :
where,
V = voltage
I = electric current
R = resistance
Now put all the given values in the above formula, we get
Therefore, the resistance in the circuit is, 2 ohm

Answer:
A) and B) are correct.
Explanation:
Let's take a look at the attached picture. Now
The total voltage across both capacitors is the same as the sum of the voltage from each device, that statement is true for any electrical device connected in series. So a) is TRUE
The equivalent capacitance is going to be:
And that value can be mathematically proven that is always less than any of the values of each capacitor. So b is TRUE
And through both capacitors flow the same current, but the amount of charge depends on the value of the capacitors, so only could be the same if the capacitors are the same value. Otherwise, don't. C) not always, so FALSE
