WebScience Physics Two point charges of mass m each are suspended in the gravitational field of the Earth by two non-conducting massless strings, each of length 1, attached to the same fixed point. The spheres are given equal charges Q of the same sign. As a result each string makes angle a to the vertical (see figure below). Calculate m, if 1 = 78.3 cm, Q = 4 µC … WebOhm’s Law Calculator. Use Digi-Key’s Ohm’s Law calculator to calculate the relationships between current, voltage, resistance, and power in simple resistive circuits. Enter at least any two input values and click calculate to solve for the remaining values. Reset the calculator after each calculation for best results. Voltage (V) V ...
What is Earth Resistance? Definition & Explanation
WebWhen you have only two resistors in parallel, the equivalent resistance can be easily calculated using this equation: Req = R1 × R2 R1 + R2 R e q = R 1 × R 2 R 1 + R 2 Applications for Parallel Resistors Resistors in parallel … WebUse our formula, Earth Conductor size = √ (20000 2 x 0.5) / 80 = 20000 x 0.707 / 80 = 176.8 Sqmm Approximately 185Sqmm.
