Formulas for Electricity in 8th Grade Physics

In 8th grade physics, you will learn about various concepts related to electricity. Here are some formulas that are commonly used in this topic:

1. Electric Charge (Q) - The formula for electric charge is Q = c * m * (t2 - t1), where Q represents the electric charge, c is the specific heat capacity, m is the mass of the substance, and (t2 - t1) is the change in temperature.

2. Electric Current (I) - The formula for electric current is I = Q / t, where I represents the electric current, Q is the electric charge, and t is the time taken.

3. Voltage (U) - The formula for voltage is U = 220V, where U represents the voltage.

4. Resistance (R) - The formula for resistance is R = U / I, where R represents the resistance, U is the voltage, and I is the electric current.

5. Ohm's Law - Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. Mathematically, it can be represented as V = I * R, where V is the voltage, I is the electric current, and R is the resistance.

Please note that these formulas are just a few examples of the concepts covered in 8th grade physics. There may be additional formulas and concepts that you will learn as you progress in your studies.

I hope this helps! Let me know if you have any further questions.
