The relationship between voltage, E, current, I, and resistance, Z, is given by the equation E = IZ. If a circuit has a current I = 3 + 2i and a resistance Z = 2 – i, what is the voltage of the circuit? 4 – i
1 answer:
E=IZ=(3 + 2i)(<span>2 – i)=3*2-3i+2i*2-2i*i =6 - 3i+4i -2i² =6</span>-2i² - 3i+4i =6+2+i=8+i <span>i²=-1 </span>
