Two resistors, A and B, are connected in a series circuit with a battery. The resistance of A is twice that of B. Which resistor
1 answer:
Answer:
A dissipates more power.
Explanation:
- In a series circuit, the current is the same at any point in it.
- The power dissipated in any resistor follows Joule's law, as follows:
- So, for a given current, the power is directly proportional to the resistance of the resistor.
- In this case, as resistor A has twice the resistance of resistor B, A dissipates twice more power than B.

Answer:
The speed of the particle is 34.66 m/s.
Explanation:
Given that,
Mass of particle = 50 g
Charge of particle = 4.0 mC
Velocity = 25 m/s
Electric field = 60 N/C
Time = 5.0 sec
We need to calculate the speed in y direction
Using formula of speed
Where, a = acceleration
Put the value in to the formula
We need to calculate the speed of the particle
Put the value into the formula
Hence, The speed of the particle is 34.66 m/s.
