omeli [17]

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

a ferry which runs at 12m/s in still water travels between towns a and b on a river which flows south at 9 m/s. the ferry leavs

Reil [10]

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 $v_b=12\hat{i}$

velocity of stream $v_s=-9\hat{j}$

now relative velocity of boat w.r.t. stream $v_{b/s}=12\hat{i}+9\hat{j}$

this velocity with which ac distance will be covered.

therefore magnitude of $v_{b/s} =\sqrt{12^2+9^2}$

= 15 m/s

A parallel circuit has three branches. Each branch has a resistance of 37.5 ohms. The total current is 7.5 amps. What is the cur

Sophie [7]

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 $\frac{7.5}{3}=2.5A$
