Circuits: Voltage (Potential Difference), Current, Resistance, Ohm’s Law, Parallel & Series Circuits, Power & Energy
| Front | If a circuit is parallel, what happens to the current? Voltage? |
| Back | Current splits between branches depending on resistance; Voltage remains constant across bands |
| Front | Equations to solve for Power in watts (W)? |
| Back | P=I2×RP = I^2 \times R When current and resistance are knownP=V2RP = \frac{V^2}{R} When voltage and resistance are known |
| Front | Shortcut to find equivalent resistance across 2 parallel resistors? |
| Back | Req=R1R2R1+R2R_{eq} = \frac{R_1 R_2}{R_1 + R_2} |
