- A 20-Ω resistor is connected to four 1.5-V batteries. What is the joule heat loss per minute in the resistor if the batteries are connected … (a) in series and … (b) in parallel?(a) When measuring the voltage across a resistor and the current through it, the voltmeter and the ammeter should be connected in respectively, to the resistor. series and series series and parallel O parallel and series O parallel and parallel (b) The resistances of an ideal voltmeter and ammeter should be infinity and zero infinity and infinity zero and infinity zero and zero respectively. Hint: Voltage is the measure of difference of the potential between two different points. Current is the measure of the flow of electrons.I need help on problem 33)Consider the resistor described in problem 1 carrying a current of 1 mA. If the voltage drop across the resistor is 25:0 Volts, what is the resistance (in k )? (b) Electrical currents crossing the human body in excess of 0.3A are typically deadly. If electrical current has a direct pathway to the heart, it can interfere with your heart beat. In such a case, it only takes about 1 mA to be deadly. Fortunately, under dry conditions, the hand-to-hand resistance of the human body can be as large as 100,000 : This is primarily due to the resistance of your skin. Unfortunately, if your skin is wet or chapped, your resistance can be as low as 1000 . If you touch a 9 Volt transistor radio battery, placing one hand on the positive electrode, and the other hand on the negative electrode, what will be the current passing through your body with dry skin? With wet skin?
- The circuit shown below can be used to measure the resistance of a platinum resistance thermometer (PRT). AB is a uniform resistance wire of length 1.00 m and C is a sliding contact on this wire. A standard resistor R is included in the circuit. The position of C is adjusted until the voltmeter V reads zero. (ii) The PRT consists of 9.00 m of wire of diameter 8.4 × 10-2 mm. The voltmeter reads 0 V when l1 = 0.422 m. If the standard resistor, R, has a resistance of 220 Ω, what is the resistivity of platinum? Show that you have checked that the value for the resistivity and its unit are sensible.(d) Finally, consider the following circuit constructed with both copper (blue) and nichrome (orange) wires. + Assume all wires in the circuit have a diameter of 1.024 mm. If the total length of copper wire is 25 cm, the total length of nichrome wire is 115 cm (this wire is coiled so the length is greater than it appears in the figure), and a voltage of 1.5 V is applied to the circuit, what current will flow?
