Question

CAN I GET ANSWERS PLEASE, I TRY THE FORMULA AND MY TEACHER HAS A FAMILY EMERGENCY SO HE CANT RESPOND BACK SO PLEASE HELP ME

Answer 1

Step-by-step explanation:

I won't answer each of these, but will give you an explaination of how to solve for each.

You'll need to use Ohm's Law and Kirchhoff's Voltage Law.

Remember Ohm's Law as
`V = IR`.

Kirchoff's Voltage Law says that the sum of voltages for a given circuit "loop" must equal zero. In the circuit shown, this means that the voltage provided by the battery (E_T) equals the voltage drop across each of the three resisters in the loop.

`E_T = E_1 + E_2 + E_3`

A couple of other helpful notes:

These three resistors are in series which means that the current flowing through them is equal.

So it is easy to see that...
`V = IR \rightarrow E_1 = 4*2 = 8 V`

Solve for the voltage across E_2 and E_3. The sum of the three voltages equals the voltage of the battery (E_T).
