Answer:
Explanation:
Possible causes for overcurrent include short circuits, excessive load, incorrect design, an arc fault, or a ground fault. Fuses, circuit breakers, and current limiters are commonly used overcurrent protection (OCP) mechanisms to control the risks

Brain-list it or support me at my U-Tube channel " ZK SOFT&GAMING " I will be thankful
Answer:
- Waves with higher amplitude transfer HIGHER energy.
- Waves with higher frequency transfer HIGHER energy.
Answer:
= 15 m/s
Explanation:
Considering right side(west) as positive x-axis and south as negative y-axis.
velocity of boat in still water 
velocity of stream 
now relative velocity of boat w.r.t. stream 
this velocity with which ac distance will be covered.
therefore magnitude of 
= 15 m/s
Left. Use right hand rule. Have hand wide open. Thumb points in direction of current.(which makes right angle with your index finger) Four fingers in direction of magnetic field and your palm should point in the direction of the force
Answer:
Current in each branch will be 2.5 A
Explanation:
We have given that a circuit has three branch each has a resistance of 37.5 ohm
We have also given that a total current of 7.5 A is flows through the circuit
As we know that in parallel circuit total current is the sum of current flowing through each branch
As the resistances of each branch is same so current will also be same
As there is 3 branches in circuit so current in each branch will be
