What to Focus On
- Static electricity is produced by friction between materials
- Two types of charges exist: positive and negative
- Like charges repel, unlike charges attract
- Electric potential is work done per unit charge
- SI unit of potential is volt (V)
- Potential difference causes current to flow
- Current is charge flow per unit time
- SI unit is ampere (A)
- Conventional current flows from + to - terminal
Common Mistakes to Avoid
Current flows from negative terminal to positive terminal of a battery
In parallel combination, total resistance is greater than individual resistances
Voltage gets divided in parallel circuits like in series circuits
Memory Tips
Like charges repel, unlike charges attract
Coulomb's Law formula F = kq1q2/r²
Electric current flows from positive to negative terminal
Ohm's Law V = IR
