6 Σεπ 2024 · Direct Current (DC) is a type of electric current that flows in only one direction. It is the opposite of Alternating Current (AC), which periodically changes direction.
The number of water molecules that flow in the river and falls must be equal to the number of molecules that flow over each waterfall, just like sum of the current through each resistor must be equal to the current flowing into the parallel circuit.
Suppose you are doing a physics lab that asks you to put a resistor into a circuit, but all the resistors supplied have a larger resistance than the requested value. How would you connect the available resistances to attempt to get the smaller value asked for?
Answers to practice questions . AQA Physics . Question Answer Marks Guidance . 1 (a) three resistors drawn in series 1 The largest resistance is when the resistors are all connected in series. 1 (b) R = 3.0 + 4.0 + 6.0 = 13 Ω 1 1 (c) three resistors drawn in parallel . 1 Adding resistors in parallel creates extra paths for the current and thus ...

Current is the flow of charge; thus, whatever charge flows into the junction must flow out. Kirchhoff’s second rule, also known as the loop rule, states that the voltage drop around a loop is zero. 10.5: Electrical Measuring Instruments. Voltmeters measure voltage, and ammeters measure current.
31 Ιαν 2023 · There are two basic direct current circuits of importance to us: those with two or more resistors connected in a series, and those with two or more resistors arranged parallel to each other. Other direct current circuits can be understood in terms of these two basic circuits.
