What charge do humans have? Resting cells are negatively charged on the inside, while the outside environment is more positively charged. This is due to a slight imbalance between positive and negative ions inside and outside the cell. Cells can achieve this charge separation by allowing charged ions to flow in and out through the […]

How is sound waves measured?
How is sound waves measured? Sound energy travels in waves and is measured in frequency and amplitude. Amplitude measures how forceful the wave is. Frequency is measured in the number of sound vibrations in one second. A healthy ear can hear sounds of very low frequency, 20 Hertz (or 20 cycles per second), to a […]
What is the difference between EMF and back EMF?
What is the difference between EMF and back EMF? The back emf is represented as a variable emf that opposes the emf driving the motor. Back emf is zero when the motor is not turning and increases proportionally to the motor’s angular velocity. The generator output of a motor is the difference between the supply […]
Why thick wires are used in transformer?
Why thick wires are used in transformer? When a transformer is in operation, there are ac currents in primary and secondary coils. This is the most important for the high current winding (the secondary coil of a step-down transformer). Thick copper wire is used for this winding, because thick wire of low resistivity has a […]
