Flow-through current
WebMay 26, 2024 · The sweet spot turned out to be a felt of nickel microfiber that produced more hydrogen than the nanowire felt, despite having 25 percent less surface area for the reaction. Over the course of a 100-hour test, the microfiber felt produced hydrogen at a current density of 25,000 milliamps per square centimeter. At that rate, it would be 50 … WebInstructions. Take a look at the illustration of a battery, looped with a wire coil and a simple motor on parallel circuits. The yellow dots are electrons representing the flow of electricity. Observe the readings on the flow meters, which show current in amps. See how the flow is affected by the resistance from the wire coil and the motor.
