Lesson-12.1.3- describe the qualitative effect of changing resistance on the current in a circuit. | the qualitative variation of resistance of light-dependent resistors (LDRs) with illumination and thermistors with temperature.PreviousLesson-12.1.5- know and use the relationship between voltage, current and resistance: voltage = current ?? resistance V = I ?? R | know that current is the rate of flow of chargeNext
