the voltage drop across each resistor will be directly proportional to the size of the resistor. In a parallel circuit, the voltage drop across each resistor will be the same as the power source.
Ohm's Law can be rewritten in three ways for calculating current, resistance, and voltage. If a current I should flow through a resistor R, the voltage V can be calculated. First Version of the (voltage) formula: V = I × R If there is a voltage V across a resistor R, a current...
Let us consider a circuit featuring a single ideal battery connected across a pure resistor. As the battery is ideal, it has no internal resistance. Under these circumstances, the voltage drop across the resistor is independent of its resistance and is equal to the constant EMF of the b...
Combinational resistor circuits that are powered by a single voltage source can be simplified by the equivalent resistance method or by converting the combinational circuit into a series circuit and then applying the voltage divider rule. Answer and Explanation: To investigate the current flow...
Selecting the Current-Sense Shunt ResistorIt is critical to determine the optimum value for the current-sense resistor (RSENSE). Larger RSENSE values increase the series IR voltage drop and power loss; however, this would also minimize the effect of the offset voltage error, as...
To calculate output voltage from a circuit, use Ohm's law. Voltage is measured in volts, current is measured in amps and the resistance is measured in ohms. The formula needed is V = I x R. You can use this formula in both parallel and series circuits.
C18 = 0, resistors designed for proper voltage range. The topology is wrong. Normally, you wire the internal error amplifier as gain = -1, which would be done with resistors like so:Which leads to the next parts,D15: omit (replace with short), add resistor across opto (pins 1-2), ...
Why would you not also add a 1 or 1.5 ohm resistor to the 10uF case? If you can afford that much voltage drop (I guess your total load is some 100-200 mA max?), I guess it wouldn't hurt to save a little inrush while you're at it, eh?

It is critical to determine the optimum value for the current-sense resistor (RSENSE). Larger RSENSEvalues increase the series IR voltage drop and power loss; however, this would also minimize the effect of the offset voltage error, as shown in Table 2. For designs that ma...
