Electrical systems are governed by Ohm’s law, which states that V = IR, where V is the voltage, I is the current, and R is the r
esistance. If the current in an electrical system is decreasing at a rate of 8 amps per second while the voltage remains constant at 24 volts, at what rate is the resistance increasing (in ohms per second) when the current is 56 amps?
Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax.
