Ohms Law and transposition

Which is the correct transposition of the formula to the left?

• I = ER

• R = ^I/_E

• I = E - R

• R = ^E/_I

Which is the correct transposition of the formula to the left?

• P = RI²

• P = IR²

• I = ^R/_P

Which is the correct transposition of the formula to the left?

• R = IP

• P = R²I

• R = I² + P

• P = RI²

Which is the correct transposition of the formula to the left?

• E = IR

• R = E/I

• E = RI

• all of these

In electrical notation, R = resistance and P = power but what do E and I stand for?

• E= electricity and I = internet

• E= electrons and I = current

• E= voltage and I = current

• E= velocity and I = current
