ELECTRICAL POTENTIAL AND CURRENT: V = IR E = Pt P = IV C = rPt Parallel Circuits: Series Circuits: Vy= V₁ + V₂ + V₂ + ... V₁ = V₁ = V₂ = V₂ =... 17 = 1₁ = 1₂ = 1₂ =... 17 = 1₁ + 1₂ + 1₂ + ... 1 1 1 1 R₁ = R₁ + R₂ + R₂ +. + + Ry R₁ R₂ R₂ Based on the circuit drawn below: (Please use your VIRP chart) R₁ = 152 V = 120 V R₂ = 2002 R₁ = 52 a) What is the value for RT (Total Resistance)? b) What is the total Current IT?
c) What is the potential difference V₂across R₂? d) If the same 3 resistors were arranged in parallel with the same battery (voltage), would the total Resistance RT (equivialent resistance) for the circuit increase, decrease or remain the same? Simple Electromagnet -iron nail colled wire wire Battery battery VectorStock e) A physics teacher takes some of the wire used to create the given circuit and uses it to make an electromagnet by wrapping it around an iron core and connecting it to a voltage source. Describe one way to increase the strength of the electromagnet.
