The UHS MDCAT syllabus includes the following topics from Current Electricity:

1. Electric Current
   • Definition & formula: I=QtI = \dfrac{Q}{t}I=tQ​
   • Drift velocity and current density
2. Ohm’s Law
   • Relationship between V, I, R
   • Conditions for validity
3. Resistance and Resistivity
   • Formula: R=ρLAR = \rho \dfrac{L}{A}R=ρAL​
   • Factors affecting resistance (length, area, temperature)
4. Combination of Resistors
   • Series & Parallel networks
   • Effective resistance calculations
5. Electrical Power & Energy
   • Power: P=VI=I2R=V2RP = VI = I²R = \dfrac{V²}{R}P=VI=I2R=RV2​
   • Energy consumed: E=P×tE = P \times tE=P×t

Key Formulas of Current Electricity

• Current: I=QtI = \dfrac{Q}{t}I=tQ​
• Ohm’s Law: V=IRV = IRV=IR
• Resistance of Conductor: R=ρLAR = \rho \dfrac{L}{A}R=ρAL​
• Resistors in Series: Req=R1+R2+R3+...R_{eq} = R_1 + R_2 + R_3 + ...Req​=R1​+R2​+R3​+...
• Resistors in Parallel: 1Req=1R1+1R2+1R3+...\dfrac{1}{R_{eq}} = \dfrac{1}{R_1} + \dfrac{1}{R_2} + \dfrac{1}{R_3} + ...Req​1​=R1​1​+R2​1​+R3​1​+...
• Electrical Power: P=VI=I2R=V2RP = VI = I²R = \dfrac{V²}{R}P=VI=I2R=RV2​
• Work/Energy: W=VItW = VItW=VIt
