What is the p. d. across a 4 resistor when there is a current of 0.3 A in it?

1.2V

Explanation:

Given parameters:

Resistance  = 4Ω

Current  = 0.3A

Unknown:

Potential difference  = ?

Solution:

To find the potential difference, we use the ohms law;

              V = IR

Now, insert the parameters and solve;

       V = 0.3 x 4  = 1.2V

the first, second, and fifth options

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
