where VS = potential difference across the Secondary coil (units: V) where VP = potential difference across the Primary coil (units: V) where NS = number of turns in the Secondary coil where NP = number of turns/ windings in the Primary coil 物理公式英文:放射性Radioactivity 放射衰变定律 半...
Physics and Natural Law A word perhaps is needed about the difference betweengasesandliquids, though the difference is easier to perceive than to describe. In gases the molecules are sufficiently far apart to move almost independently of one another, and gases tend to expand to fill any volume ...

How does a simple pendulum work?Changes in potential and kinetic energy as a pendulum swings. See all videos for this article pendulum, body suspended from a fixed point so that it can swing back and forth under the influence ofgravity. Pendulums are used to regulate the movement ofclocksbec...
During the process, the current flowing in the circuit and the corresponding value of potential difference across the resistance wire R are recorded. This way different sets of values of voltage and current are obtained. For each set of values of V and I, the ratio of V/I is calculated....
Resistance (R1) = 10 Ω Resistance (R2) = 15 Ω Potential difference (V) = 5 V To find: Total resistance of the circuit (Rs) Potential difference across the 15 Ohms resistor (V2) Formula: Rs = R1 + R2 V2 = IR2 From the circuit diagram, the two resistors are connected in seri...
Searching for the explicit solutions of the potential function in an arbitrary resistor network is important but difficult in physics. We investigate the problem of potential formula in an arbitrary m × n globe network of resistors, which has not been resolved before (the previous study only...
Potential formula of an arbitrary resistor network has been an unsolved problem for hundreds of years, which is an interdisciplinary problem that involves many areas of natural science. A new progress has been made in this paper, which discovered the potential formula of a nonregular m × ...
