 10TH SCIENCE PASSING PACKAGE 

PART - PHYSICS 

CHAPTER - ELECTRICITY 

SI UNITS

→ electric current (I) - Ampere (A)

→ Resistance (R) - Ohm (Ω):  

→ Electric charge (Q) - Coulomb (c)

→ electric potential (voltage) - Volt (v)

 → Electric power (P) - Watt (w)

→ work or energy (W) - Joule (j)

 EQUATIONS

→ Current = Charge/Time ⇒ I = Q/T

→ Potential difference = work done/Electric charge ⇒V = W/Q

IMPORTANT TERMS:

→ Current (I): The rate of flow of charge is called current.

→ Potential Difference (V): Work done to move a unit charge from one point to another.

→ Voltmeter: It is an instrument to measure the potential difference. always connected in parallel.

→Ammeter: It is an instrument to measure the current. always connected in series.
