**Unformatted text preview: **power for 1 hour. Circuit diagram - a way of drawing electrical circuit using standard symbols. Series circuits - a circuit in which the loads are connected end to end so that there is only one path for electrons to flows. Parallel circuits - a circuit in which the loads are connected by branches so that there are 2 or paths for electrons to flow. Electrical current (I) - a measure of the rate of electron flow past a given point in a circuit; measured in amperes Ammeter - a device used to measure electric current. Potential difference ( voltage (V) ) - the difference in electrical potential energy per unit charge measured at two different points; measured in volts (V) Electrical resistance ( R ) - the ability of a material to oppose the flow of electric current; measured in ohms ( ). Ω Ohmmeter - a device used to measure resistance Ohm’s law - the straight-line relationship between voltage and current; r equals v divided by i...
